• Using the MANAGE MODE command
fileattr
, verify that:
• ADMIN has READ/WRITE access to CONFIG files
• ADMIN has READ/WRITE access to OTHER files
• Exit MANAGE MODE by typing
exit
<RET>.
3. Using the TFTP client on the remote workstation, TFTP the
UPGRADE.OSW
file to the
CyberSWITCH in binary mode. Be sure to include the file’s full pathname. The exact method
to transfer varies, depending upon your TFTP client.
Note: If you experience a transmission timeout, check the retransmission setting on the TFTP
package. A retransmission rate of 10 seconds is usually sufficient; values less than that
may not work properly.
If you experience a problem transferring the file with TFTP, wait about three minutes
for the TFTP to fail, delete the incomplete file, and try again.
4. Using Telnet, reboot the system by issuing the command:
restart
It should take approximately 3 minutes for the system to restart and install the upgrade.
5. Login via Telnet and type the
ver
command to confirm that the system software upgraded
correctly. If the upgrade did not occur, check the system log with the
dr
command to find any
potential problems, and retry.

The system is preconfigured with defaults that were designed to make it possible to have your
system up and running quickly. After your machine is functioning properly, some of these defaults
should be changed to make your system more secure. The following configuration changes are
needed to provide this security:
1. Either delete User1 and User2 or change their names and secrets.
Use Dynamic Management’s manage mode to carry out either of these functions. To enter the
manage mode, type
manage
at the system prompt. If you have no need for these types of
devices (PPP devices), simply delete these two devices. At the manage mode prompt, enter the
following command:
device delete
Follow the on-screen instructions for deleting each device.
To change the preconfigured devices’ names and secrets to secure the access to the system,
enter the following command at the manage mode prompt:
device change
Follow the prompts to change the device name and secret for User1 and User2. After you have
either deleted or changed the device information, make these changes permanent by entering
the
commit
command
